MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic. These links are presented in a way that suggests they are book downloads, but the ML_NYX_PDF_MALICIOUS classifier indicates a high probability of malicious intent. The embedded URLs, while many are marked as confirmed benign, are part of a link farm strategy. The primary attack pattern involves social engineering users to click these links, likely leading to further malicious content or phishing attempts.

Heuristics 2

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
